I generally hate the step sequences under IJS. They're too twisty, too slow, and as my friend put it, 'just a lot of arm flailing'.

Here are two that I love:

Jeremy Abbott's LP step sequences from last year. They were so different in tone, and worked to tell a story within the program:
Are there any others? I'm curious.
